Обсуждение: User Defined Functions

Hi there,

Can anybody tell me about User Defined Functions in Postgresql? For what
I know, UDF's and in a very early state of development, am I right?

Where can I find documentation on this? What else should I know on this
matter?

Thanks!

No, UDFs in PostgreSQL are a mature feature, and have been included
for as long as I've been using the product for, at any rate.

Docs:

http://developer.postgresql.org/docs/postgres/index.html
http://developer.postgresql.org/docs/postgres/xfunc.html

As well as chapters in most of the books on PostgreSQL.

Cheers,

Neil

Thanks, this answers some of my questions
I found out that you can even write your UDF's in Perl, which are great
news (http://www.devx.com/dbzone/articles/renaker03/renaker03-1.asp)

However, I haven't found any reference to writing UDF's in Java. I
suppose it's possible. Am I wrong? How is UDF writing in other languages
than C/C++/SQL supported?

thanks!
